did you actually read it?
to answer your question the fact that a solar powered plane can fly at night is testament to the progression of solar technology!
or read the topic title it says something about solar panels does it not?

I did read it - it's a story I've been following for some time and it's a great achievement; what I asked was what relevance it has to heating and powering homes in the UK, and the answer - if you care to think about it - is very little.
To gain the power needed to store in the bloody great batteries that thing carries so it ca fly at night it needs to fly in the day; it has a major advantage in that it is not a house, it's an aeroplane. Unless you can elevate your necessarily south facing roof to above the cloud base when the sun isn't shining you're stuffed; the aeroplane isn't.
It's logical when you think about it.
